Embodiment 1
[0040] figure 1 The dynamic process is that when the special welding device 1 walks along the weld seam in the curved panel row placed on the displacement mechanism 3, the digital angle measuring instrument 2 simultaneously and real-time and the inclination angle in the Y direction are measured, and the measured inclination angle information is transmitted to the operation control system 4, and the operation control system 4 generates a control command signal after analyzing, processing, and distinguishing the collected inclination angle information, Under the control of the control command signal, the X-axis rotation mechanism and the Y-axis rotation mechanism of the displacement mechanism 3 are rotated in directions tending to be smaller in angle, until the tilt angle measured by the digital angle measuring instrument 2 reaches a preset value. Within the range of the set allowable inclination angle (0~±n°), the angle measurement and control process is continuous, so that the...

The invention relates to a position-changing mechanism for an automatic curved-surface plate column welding method. The position-changing mechanism is characterized in that a base is provided with an upper rotating table and a lower rotating table, the upper rotating table is provided with a welding device, and the welding device is provided with a digital angle measuring instrument; and the lower rotating table is connected with the base through a rotating shaft, a first driving device is arranged between the base and the lower rotating table, the upper rotating table is installed on the lower rotating table through bearings and bearing bases, a second driving device is arranged between the upper rotating table and the lower rotating table, and a transverse and longitudinal two-dimensional rotating position-changing mechanism is formed by the upper rotating table and the lower rotating table. According to the position-changing mechanism, by means of effective control of digital angle measurement and welding-seam curved angle adjustment, the technical problem of changing curved welding seam oblique position welding into horizontal position welding is solved, automation of curved welding seam welding is achieved, and therefore the welding quality and efficiency can be greatly improved, and the labor intensity of workers is reduced.
Description
technical field [0001] The invention relates to the technical field of automatic welding, in particular to a displacement mechanism and a welding method for an automatic welding method of curved panel rows in curved surface segments in hull construction. Background technique [0002] The hull construction of a ship takes the segment as the basic unit, and the segment can be roughly divided into two types: curved surface segment and straight segment. The straight segment is basically a rectangular structure. It tends to be linear, and most of them are straight welds. At present, it is mainly automated welding production in the form of plane segmented production lines. However, the segmented surface welds and longitudinal bone welds are curved welds, which belong to large inclined position welding for welding, and welding is difficult, especially it is difficult to realize automatic welding production. The reasons are attributed to 1) When the weld seam is welded in a large i...
